Essentially is just

$\bf \cfrac{8}{9}\div \cfrac{2}{3}\implies \cfrac{8}{9}\cdot \cfrac{3}{2}\implies \cfrac{8\cdot 3}{9\cdot 2}\implies \cfrac{24}{18}\implies \cfrac{4}{3}
\\\\\\
\cfrac{7}{8}\cdot \cfrac{1}{4}\implies \cfrac{7\cdot 1}{8\cdot 4}\implies \cfrac{7}{32}
\\\\\\
\cfrac{3}{4}\cdot \cfrac{1}{6}\implies \cfrac{3\cdot 1}{4\cdot 6}\implies \cfrac{3}{24}\implies \cfrac{1}{8}$

Mathematics

By definition, the arc length is given by:
S = R * Theta
Where,
R: radio
Theta: central angle
Substituting values we have:
(7/3) π = (6/2) * Theta
Clearing the angle we have:
Theta = (7/9) π
Rewriting the angle in degrees:
Theta = (7/9) π * (180 / π)
Theta = 140 degrees

The measurement of a central angle (in degrees) is:
Theta = 140 degrees
D) 140 °
